Farid Essebar (Arabic: فريد الصبار) (born in 1987, known as Diabl0) is a Moroccan black hat hacker. He was one of the two people (along with Turk Atilla Ekici) behind the spread of the Zotob computer worm that targeted Windows 2000 operating systems in 2005. Among the affected were CNN, ABC News, The New York Times, Caterpillar, United Parcel Service, Boeing and also the United States Department of Homeland Security.
Microsoft used 50 investigators and had put a $250,000 reward for the capture of the hacker(s). Microsoft's General counsel declared on 26 August 2005 that "The fact that we were able to see these arrests in less than two weeks and see them halfway around the world really drives that point home."
Essebar is a Russian citizen, also.[1]
